Dress and true the wheel
Always dress and true the resurfacer wheel face to keep it in propergrinding condition. Never dress or true a wheel above the wheel centerline. In addition, always dress or true the wheel as close as possibleto the point of actual grinding. Since the grinding wheel usually wearsmost often on the edges, start truing at the center of the wheel faceto prevent excessive penetration and consequent damage to the diamondtool. Diamond tool holders and mechanical wheel dressers should beclamped securely to the table and well supported to eliminatevibration, which could cause knicks on the grinding wheel. In precisiongrinding, the better the truing or the dressing, the better the finishwill be.

Use the proper wheel speed
Wheel speed can affect the wheel and surface finish of the workpiece. To obtain a good finish, use light cuts and a slow table traverse; bothin wheel truing and in the final grinding operation.

Use grinding fluid
Grinding fluid is important for good grinding operation. Use a generousflow of fluid at the point of contact between wheel and workpiece.Always turn on the fluid flow and start work rotation before startingto grind. Keep fluid clean! Dirty grinding fluid is the enemy of goodworkpiece finishing. To prevent cracks in hardened steel, use a freecutting grinding wheel with a generous flow of fluid.
